Description

Overwriting management method and method of recording management information of a single optical disc writing.

Technical field

The present invention relates to a method of overwriting management and an information recording method management on a single write optical disk.

Prior art

Currently, there are development expectations and production of a new HD-DVD (Versatile Disc High Density Digital) in which it will be possible to write and store a large amount of video data and audio data from high quality, for example, the BD-RE (Disk Blu-ray Rewritable).

As shown in Figure 1, the BD-RE is divided into a LIA (zone of introduction), a data zone and a LOA (exit zone). At start and end of the data zone are arranged so separated an ISA (reserved inner zone) and an OSA (reserved zone Exterior).

The BD-RE records data in the unit of a cluster that corresponds to a recording unit specific and, as shown in figure 1, it is detected if there is a defect zone in the data zone during the data recording If a defect zone is detected, it is carried performed a series of substitution recording operations for make a replacement recording of the data recorded in the defect zone in the unit of a cluster of a reserved zone, for example, an ISA. Also, the position information of the Defect zone and recording position information of replacement in the reserved area are recorded and stored as management information in a list of defects in the area of introduction.

Thus, even if there is an area of defects in the data area of the BD-RE, the data Engravings in the defect zone are recorded in replacement in the zone reserved and, during the playback operation, the data recorded substitutions in said reserved area are read and reproduce, instead of reading and reproducing the data of the zone of defects, referring to management information, so that it is possible to avoid in advance any error in the data recording / playback

Meanwhile, the standardization of BD-WO (Single Blu-ray Disc writing) has recently been discussed by companies interested and, because said BD-WO only can be recorded once on the entire surface of the disc, it turns out physically impossible to overwrite a BD-WO, to difference from BD-RE.

However, it may be necessary overwrite a BD-WO to edit the data recorded, to modify a part of the recorded data or to obtain advantages for the user or the equipment, so that there is a  urgent need to find a solution to this problem.

The document US-A-5 448 728 refers to a control system of a storage medium to control a single write and multiple read storage media, in the that an operator can modify and update the stored data in said medium and easily manage said modified data and said data updated in the middle. The system is configured so that it has a first and second search units, a writing unit and a reading unit. The function of the First search unit is to search for an unwritten area next to one last zone with data written in a storage area of data from the storage medium, and the function of the unit Writing is reading the data stored in the searched area. The function of the second search unit is to search for a last zone with data written on the storage medium, and the function of The reading unit is to read the data of the searched area.

The document EP-A-1 564 740 (document under Art. 54 (3) EPC) refers to a recording medium that it consists of a single writing recording medium that has data rewriting capacity. In response to a request from write data to an address where data has been recorded, the data recorded is recorded in a subzone substitution of rewrite (OSA), and replacement management information that associates the original address with the address in the subzone of rewrite substitution is recorded in the management subzone of substitution (ISA).

Best way to carry out the invention

Reference will be made below detailed to the method to manage the overwrite of a disk single write optic according to the preferred embodiments of the present invention, showing examples thereof in the accompanying drawings In cases where possible, in the drawings will use the same reference numbers for reference the same elements or similar elements.

The present invention makes it possible to overwrite even a single write optical disc. The term "overwrite" means repeated recording in a zone specific to a rewritable optical disc. In other words, the overwriting simply constitutes the inherent characteristic of a rewritable optical disc, and it is generally known that it is impossible to overwrite a single optical disk writing.

However, the present invention makes possible carry out a logical overwrite while maintaining the physical characteristics of the single optical disc writing.

Figure 2 shows a method to manage the overwriting a single write optical disk according to a embodiment of the present invention. For example, him BD-WO (Single Blu-ray Disc writing) includes a LIA (introduction zone), a zone of data and a LOA (exit zone). At the beginning and at the end of the data zone can be arranged separately an ISA (indoor reserved area) and an OSA (outdoor reserved area).

Also, a TDMA (zone of temporary defect management). A TDFL (list of defects temporary) is recorded in the TDMA, and a default input or a overwrite input is recorded in the TDFL as information from management. Accordingly, in the case where the data of the corresponding zone are recorded in substitution in another zone of the data zone due to the defect zone or by a request for overwrite, the management information is recorded as the TDFL in the TDMA

In figure 2, if in the data zone it already exists a recorded area, it is not allowed to physically carry out a "overwrite" in the corresponding zone, due to the characteristics of the single write optical disc. Do not However, if a recording order from the user or the equipment request to carry out the recording in an A-B zone (for example, in an already recorded area), as shown in the Figure 2, the present invention allows a controller to perform by itself recording data substitution in another area of the data zone Accordingly, the user or the team can Sort the recording regardless of whether the specific zone of the disc is recorded or not and, therefore, the user can use the single write optical disk as an optical disk rewritable This is called logical overwrite (LOW), to Difference from physical overwrite.

Specifically, as shown in the Figure 2, when carrying out the recording order in the zone A-B, it is not possible to overwrite the corresponding area, because it is already a recorded area. In change, the recording order can be carried out so that the data is recorded in substitution in a C-D zone, in front of an OSA (outside reserved zone) of the data zone, recording the corresponding management zone in the TDMA of the disk such as TDFL information. Then, if the user or the team orders the reproduction of data in the area A-B of the disk, the controller reproduces the data stored in the C-D zone, instead of playing the data in zone A-B, referring to the recorded management information.

Figures 3, 4A, 4B and 5 show the different areas in which the recording of replacement by a rewrite order, and figures 6 to 12 show methods for recording management information in areas of overwriting or consecutive defects according to the embodiments of The present invention. It should be noted that the drawings show they will use the same reference numbers to refer to the same elements or similar elements.

Figure 3 shows a method to manage the overwriting a single write optical disc according to another embodiment of the present invention. This realization is characterized in that the data of the area in which the overwrite are recorded in replacement to track data already Engravings This embodiment is equal to the embodiment of the figure 2, except for the area recorded in substitution.

Figure 4A shows a method to manage the overwriting a single write optical disc according to another further embodiment of the present invention. This realization is characterized in that the data of the zone (for example, the zone A-B) in which the overwrite is requested is they record in substitution in the C-D zone, in the zone reserved. Therefore, in the reserved area, a cluster is recorded replacement due to the defect zone and a cluster of replacement due to the overwrite request. As it will explain then this means that the recording of replacement due to the overwrite request can be treated in the same way as the replacement recording due to the zone of defects. Also, as shown in Figure 4B, the OSA can be divided into a zone for defects and a zone for overwrite

Figure 5 shows a method to manage the overwriting a single write optical disc according to another embodiment of the present invention. In figure 5, the data a record in the zone (for example, in zone A-B) in the one that the overwriting is requested are recorded in replacement in the C-D zone, in a reserved overwrite zone (OWA) That is, the reserved area ISA or OSA is the area recorded in replacement when the defect zone occurs, and the OWA is the recorded area in substitution when overwriting is requested. From accordingly, the replacement recording due to the zone of defects and recording substitution by request Overwriting clearly discriminate against each other.

Figures 6 to 12 show methods for recording management information according to the related technique and according to the present invention Referring to figure 6, a method to burn management information to disk BD-RE according to the related technique in comparison with the method to record management information in a BD-WO according to the present invention.

Defect information is recorded on the LIA of the disk, and is composed of a list header of defects and a defect entry. The list header of Defects includes identifier (ID) information with information about the list of defects and information indicating the number of default entries. A default entry is composed of 8 bytes, and includes four fields: "status1", "first PSN (physical sector number) of defective cluster ", "status2" and "first PSN (physical sector number) cluster replacement. "In a BD-RE, information on "status1" indicates information about the type of entry of default. For example, if its value is "0000b", it is an entry of defect of type RAD (defective reallocation), in which the Substitution recording is carried out normally, and if its value is "0001b", it is a default input of type NRD (reallocation not defective), in which an area of Substitution for substitution recording. In addition, the field "first defective cluster PSN" is used to record position information about the cluster in which the defect and, in general, said field is indicated as the first PSN of the corresponding cluster. Also, the "status 2" field It is a field that is not used in the BD-RE. Such as will be explained below, and according to the present invention, the management information is recorded actively using the field "status2". The "first cluster PSN field of substitution "is used to record position information on the recorded area in substitution in the reserved area due to the area of defects. In the case of a RAD type defect input, the information about the position of the replacement recording corresponding is recorded normally, but in the case of an input default type NRD, the replacement recording is not taken to out and, thus, said field is set to zero.

Figures 7 to 12 show methods for recording management information on a single write optical disk according to embodiments of the present invention. At the moment invention, the recording of management information is divided Briefly in two types. The first is to record the information management as the overwrite entry, which discriminates from the default input, as shown in Figures 8A, 8B and 9, and the second serves to record management information such as the same type as the default entry, as shown in the Figures 10 to 12. In the first, the two types of input are discriminate against each other even by classification, but in the second, the two types of input are mixed by the classification.

Next, it will be explained in detail the method for recording management information according to this invention.

Figure 7 shows a method to record management information on a single write optical disk when the replacement recording is carried out by a overwrite request according to an embodiment of the present invention. Figures 8A and 8B show the recording of information position of the area in which the overwrite is requested, position information on the recorded area in substitution e size information about the overwrite as information of management.

For example, in the present invention, for get compatibility with a BD-RE, the information management is recorded as an entry that is 8 bytes in size in the area where the default entry is recorded. In accordance with this, the management information is recorded by applying four fields, which are the same as those of the default entry. However, management information due to overwrite is called overwrite entry, as distinguished from the entry default, and an ID information is used in the entry for discrimination.

It will be explained in detail below. the overwrite entry of figure 7. First, the type information, which is not used in BD-RE existing, it is used in the "status1" field. For example, yes it is confirmed that "1100b" is used and the entry confirms the using "1100b", the system recognizes it as the "overwrite entry". That is, the value of the field "status1", which is not used in the BD-RE, is use to discriminate the input overwrite entry default In the "first defective cluster PSN" field, save the start address information (for example, the address A) of the area in which the overwriting is requested. In the "first replacement cluster PSN" field, the start address information (for example, address C) of the recorded area replacing the data zone. it's possible express such address information as the first PSN of the Startup cluster of the corresponding zone. In the countryside "status2" is recorded the size information with which Request overwrite. However, the "status2" field It is composed of 4 bits, and if the size of the area in which it request overwriting is greater than 16 clusters, it doesn't it allows to express sufficiently the size of said zone. By Therefore, if the number of clusters to be overwritten is less than 16,  Size information size_1 is recorded in the field "status2" (case 1), but if the size is greater than 16 clusters, size_1 size information is recorded in the field "first defective cluster PSN" and in the field "first PSN replacement cluster ", respectively, or is recorded in any of the fields and "0000b" is recorded in the field "status2" (case2).

Thus, if the "status1" field is "1100b", the system recognizes the overwrite entry, and if the "status2" field is "0000b", the system recognizes that the size exceeds 16 clusters and the size information is indicated through consecutive entries. If the "status2" field has a different value of "0000b", the system recognizes that clusters as large as the value obtained by converting the corresponding digital value in a decimal number correspond with the size information with which the overwrite Naturally, by recognizing the starting address and the size information, the end address of the zone Corresponding can be confirmed.

Figure 7 shows only the case in which the recorded area in substitution is located in front of the OSA. Do not However, as shown in Figures 3, 4A, 4B and 5, the area recorded in substitution may be located after the recording area (figure 3), can be located in the zone reserved (figure 4) or may be located in a separate OWA (figure 5).

Figure 8A schematically shows the TDFL structure. In the TDFL, the default entries and Overwrite entries are recorded separately. This occurs as a result of classifying entries based on the "status1" information. Also, the TDFL heading of The TDFL has additional information on the number of entries for defect and overwrite entries and therefore it is possible get information about the entries recorded in the TDFL correspondent.

Figure 8B shows a table of types of entry according to figure 7. In the table, the default entry and the overwrite input are discriminated by field "status1". Also, the overwrite entry is divided into in the case of having one entry and in the case of having two entries, according to the value of the "status2" field. If "status2 = 0000b ", it corresponds to two inputs, and the Size information can be obtained through the following entry. If "status2 = different from 0000b", the value corresponding directly reflects the size information.

Figures 9 and 10 show methods for recording management information on a single write optical disk according to other embodiments of the present invention. Figures 9 and 10 show the case in which, if overwriting is requested, the Substitution recording management information is processed as if it were the same type as the existing default entry. That is, the management information is recorded considering that the Substitution recording for the overwrite request is the same as the replacement recording due to the defect zone. In this case, it is more preferable to discriminate if the number of recording units recorded in substitution is singular or plural (clusters, in the case of a BD-WO) that discriminate if the replacement recording is due to overwriting or defect zone.

That is, according to this embodiment, the plurality of clusters are recorded in substitution in another area for a cause specific, and the management information for its management is expressed differently with respect to the management information in the case in which a recording unit is recorded in substitution. From accordingly, the reason why the plurality of clusters is record in substitution can be the overwrite according to the present invention, or the plurality of defect zones produced in the consecutive recording units. In the present invention, the Substitution recording of the plurality of consecutive clusters it is called "linear block substitution" or simply "block replacement". Instead, the recording of substitution of a cluster is called "linear substitution of 1 cluster "or simply" replacement of 1 cluster ".

According to the methods shown in Figures 9 and 10, if the user requests the overwrite of a specific zone (for example, zone A-B) of the disk or occur Consecutive defects in all corresponding areas, the corresponding data is recorded in substitution in the area C-D of the reserved area, and your information is recorded of management. Even if the replacement recording is carried out in another data zone, except for the reserved area, such as is shown in the case of overwriting of figures 2, 3, 4A, 4B and 5, it is possible to apply the method of recording information from management according to the invention as it is.

In Figures 9 and 10, the default entry is Divide into two types. The first consists of input (substitution 1 cluster) in the case where a recording unit is recorded in substitution, and the second consists of the entry (substitution of block) in the case where the plurality of recording units They are recorded in substitution. That is, the recording method of management information of figures 9 and 10 records the information management discriminating whether the replacement recording unit is "1 cluster" or "block", and the request is considered Overwriting or defect zone occurs in the unit "1 cluster" or "block".

Also, referring to figures 9 and 10, the default entry is divided depending on whether the information  Size is used as the management information. Figure 9 shows the case in which the size information is used, and the Figure 10 shows the case in which the information of size.

First, in Figure 9, in the case of the "replacement of 1 cluster", the recording information is record in the same way as in figure 7. In the case of "block substitution", the "status1" field has a value "0000b", in the same way as in the case of "replacement of 1 cluster". The classification is always applied that the default entry is recorded in the TDFL. The first base of the classification is the "status1" field, and the following is the "first defective cluster PSN" field. According to that, if the replacement recording is carried out normally, the "1 cluster replacement" and "block replacement" they have the same "status1 = 0000b" and, therefore, in the same "status1", the classification is carried out by the field "first defective cluster PSN". This is the reason why the "status1" field has the value "0000b" in the case of the "block replacement" and in the case of the "replacement of 1 cluster ". This feature will be explained in detail referring to figure 12.

Thus, the discrimination between the case of the "replacement of 1 cluster" and the case of the "replacement Block "is carried out using the" status2 "field. That is, in the case of the "replacement of 1 cluster", "status2 = 0000b", but in the case of the "replacement of block "," status2 = 0001b or 1001b ". In this case, in the In case of "block replacement", there are two entries consecutive. If "status2 = 0001b", the entry will be the first initial entry, and if "status = 1001b", the entry It will be the second successive entry. The first entry, which is "status2 = 0002b", has the original starting address of the original zone to replace and a replacement start address of the recorded area in substitution. The second entry, which is "status2 = 0001b or 1001b", has the size information size_1 of the area to be replaced.

Figure 9 shows the recording of "status2 = 0001b or 1001b "in the case of block replacement according to an embodiment of the present invention and of course it is possible use any other information that discriminates from "status = 0000b ". For example, in the case of block replacement, it is possible to obtain the same result even if it is established that "status2 = 0011b or 1011b".

Figure 10 shows the case in which the second entry in figure 9 has the end address original of the original zone and the end address of replacement of the recorded area instead of the size information used in the second entry in the figure 9. The other elements are the same as in Figure 9.

Figure 11A schematically shows the entry that is recorded in the TDFL as the management information at record management information on the optical disk of a single writing according to the present invention. All entries are managed as the same default entries (in fact, the replacement recording due to overwriting and recording replacement due to the defect zone have the same "status1 = 0000b", called default input). At TDFL heading provides the information that indicates the number of default entries for each type. In this case, the entry in the case of "block replacement" can be called BRAD (block RAD) or CDA (defective zone consecutive). This serves to indicate that in the case of "block replacement" the block RAD is the same as in the case of the "replacement of 1 cluster", which is usually it records in substitution, although the substitution recording takes out in the unit of a block, not in the unit of a cluster.

Figure 11B illustrates a table showing the input-type relationship described by doing reference to figures 9 and 10. As shown in the table, in the case of the "replacement of 1 cluster", the entry has "status2 = 0000b" and, in the case of "replacement of block ", the entry has" status2 = 0001b or 1001b ". Also, in the case where the replacement recording has been normally completed, the entry has "status1 = 0001b" (NRD or BNRD). Thus, by extension, the table can be applied to any type of input.

Figure 12 shows a method to update the TDFL of the management information recording method shown in figures 9, 10, 11A and 11B and, specifically, shows the method of recording management information in the case where classification applies.

First, considering that the TDFL was recorded as TDFL # K with 5 "1 cluster substitutions", 6 consecutive clusters that include defective zones that are correspond to defect inputs 3, 4 and 5 have been recorded in substitution as "block substitution". At that time, it will record a new entry at the time of updating the TDFK # K + 1 and, because the default inputs 3, 4 and 5 recorded in the previous TDFL # K are included in the area of the "block of replacement "of the TDFL # K + 1, do not require additional management and thus omitted in TDFL # K + 1. That is, because default entries 3, 4 and 5 can be expressed as a new BRAD type input, they are not recorded as information from TDFL management # K + 1. Accordingly, the final number of TDFL # K + 1 entries will be three, and all three entries line up first by classification, based on information from "status1" and then align in the order of positions of their original zones before replacement. Applying this system to the case of figure 12, all entries of type RAD or BRAD have the same "status1 = 0000b" in the TDFL # K + 1 and, therefore, the entries are aligned in the order of the PSN (physical sector numbers) of the original zones replaced, which is the second base of classification. Doing this, it is possible to reduce the number of defect inputs produced due to the "block replacement", which makes possible a efficient use of the optical disk management area of a single writing

Figure 13 shows a device for record / play a single write optical disc according to the present invention

The recording / playback device includes a recording / playback device to record / play a optical disk, and a computer or controller to control said device. The controller is used to supply an order of recording / playback to the recording / playback device, and said recording / playback device records / plays a specific area of the disk according to the order of said controller. He recording / playback device 10 comprises an interface 12 to communicate with the outside, an optical sensor 11 to record or play data on disk, a data processor 13 to receive the reproduced signal from the optical sensor and transform it into a desired signal value or to modulate the signal to be recorded in a signal that can be recorded on the disc, in order to transmit the modulated signal, a servo unit 14 to control the sensor optical 11 in order to accurately read the signal from the disk optical or write precisely the signal on that disk, a memory 15 to temporarily store diverse information, including management information and data, and a microcomputer 16 to control the constituent elements of the recording / playback device.

During the recording operation, all the Disk management information is read and stored in memory 15 of the recording / playback device, and said information of Management is used for recording / playback operation in The optical disk If it is necessary to record data in a specific area of the disk, the controller 20 transmits the position information to the recording / playback device, in addition to the data to Record. The microcomputer 16 of the device Recording / Playback 10 receives the recording order, and decides if the area of the optical disc in which the controller 20 wishes to record the data is already a recorded area or is an unrecorded zone, from of the management information stored in memory 15. If you decide that the area is not recorded, the microcomputer 16 carries out the recording according to the recording order of controller 20, and if decides that the area is already recorded, said microcomputer 16 records Substitute data in another zone of the data zone. From accordingly, microcomputer 16 transmits the information of position of the recorded area in substitution and the data to the unit servo 14 and the data processor 13, so that it can be carry out the replacement recording in the desired position of the disk, through the optical sensor 11.

During the playback operation, all the Disk management information is read and stored in memory 15 of the recording / playback device, and said information of Management is used for recording / playback operation in The optical disk If it is necessary to reproduce the recorded data in a specific area of the disk, the controller 20 transmits the position information to the recording / playback device. The microcomputer 16 of the recording / playback device 10 Receive the replay order, and decide if the data has been recorded in substitution in another zone of the data zone. This can Confirm using the default entry or entry overwrite recorded on the TDFL, as described previously. Accordingly, if the area you want play is not the substituted zone, the controller reproduces the corresponding zone, and transmits the information reproduced to controller 20. If the data has been recorded in replacement in another zone, the microcomputer reproduces the recorded area in corresponding substitution, and transmits the reproduced information to controller 20.
